What kind of applications can you create with MiG Calendar?
MiG Calendar Component is a Java component that will make it easy to map anything that has a time or time range to a very flexible and optionally interactive visual representation.

SQLite3Professional is a plugin for REALBasic that gives you full low level access to sqlite 3 databases. Starting from RB2005, the sqlite3 engine is include in every version of REALbasic, but due to the way it is exposed to the end user, a lot of its power and its speed arent availables. SQLite3ProfessionalPlugin has been designed to take advantage of all the real speed and real power that the new sqlite3 engine can offer.

SQLite3ProfessionalPlugin is very different from the built-in REALbasic database engine, it doesnt have built-in Database and RecordSet classes (even if its easy to create a wrapper for these classes). It is a near 1 to 1 map to the sqlite3 C api, so you can have access to every sqlite3 routine, so for example, you can interact directly with the virtual machine or you can create your own sql functions, and much more. These are very powerful concepts that cannot be added to the current REALSQLDatabase plugin.

The audience for this plugin are professional database users, that, for example, can take advantage of the sqlite3 progress handler routine to give time to other threads or to update the REALbasic GUI while a complex sql operation is in place, or that can use the sqlite3 virtual machine to build a query system with zero delay time and near zero memory requirements even if millions of rows are returned from a query.

As a real world test, we have created an sqlite 3 database with 10 columns and 200,000 rows (database size is about 200MB), and we have execute a "SELECT * from test" query.

DH: Lore Invasion puts the player into the very mind of the most lethal war machines ever to engage combat in the war-torn Earth of 2155. Connected by a remote neural link, you control your Mechanized Assault Vehicle (MAV) in a squad of allied warriors while seeking to claim soil for the faction to which youve pledged your allegiance.
Can you lead your people to peace in a harsh universe where reflexes and nerves of steel are the touchstones of victory? Or will your enemy overpower you with superior resolve and unrelenting firepower? How will you write the Lore of the future?
History will remember your era as the turning point; after 150 years of uneasy peace, the stalemate has been broken and the Earth has once again plunged into a war that will decide the future of "No Mans Land"... once known as "North America". As the Federated States and Eastern Confederation clash once more, it will be you who enters the fray at its most intense and will lead your people to victory or oblivion. The year is 2155 and the war which will decide the fate of mankind is beginning, and your courage will write the lore of the future on the soil of battle.
This battle-zone is not the Earth as you remember it: Intense radiation makes it impossible for living things to set foot on the dried, crusted surface. Instead, factions deploy cybernetically-controlled Mechanized Assault Vehicles (MAVs) which can operate quickly and lethally while being linked to the very minds of the soldiers who control them from thousands of miles away. These vehicles of battle are so closely woven into the minds of their masters that every neural impulse is instantaneously transmitted to and from the warriors. They are one, the mind and the machine.
Some choose to fight for the technologically-advanced culture of the Federated States who inculcate justice for all and believe in the power of a balanced society. Others choose the way of the fist and adopt the savage warriors path that belongs to the Eastern Confederation where might makes right. As a MAV Warrior you will have to pull the trigger with no more than a split second of warning, but for whom will you fire your weapons and aim your cannons? Choose your allegiance and lead your faction to victory.
Main features:
Persistent Online Conflict:
- DH: Lore Invasion offers a multi-faceted gaming experience that provides a rich and dynamic experience for players of all kinds. At its core, Lore Invasion offers pulse-pounding first-person action where quick reflexes and nerves of steel are the path to victory. Once the battle is done, however, game statistics and records are saved permanently to measure your factions progress and track your own history as a MAV Warrior.

Mavs and Customization:
- Choose from 4 different MAV classes including Tank, Scout, Infantry and Assault classes. After choosing a class, customize the offensive capabilities of your vehicle by arming primary and secondary weapons specifically tailored to your MAVs design and purpose. Each class also has its own special weapons, designed to compliment that MAVs design and role on the battlefields, including mines for Scouts to drop in enemy territory or to protect objectives, Flame Throwers for close in Assault class combat, deployable turrets to help protect objectives, and Tank artillery from frontline aggressors.
- When working in a squad of fellow MAV Warriors, you can tailor your MAV designs to support each other in the fray of combat, playing the strengths of each model to create a well-rounded, powerful attack team.
